The AWL9224 power amplifier is a high performance InGaP HBT IC designed for transmit applications in the 2.4-2.5 GHz band. Matched to 50 at the input and output, the part requires no additional RF matching components off-chip. The PA exhibits unparalleled linearity for both IEEE 802.11g and 802.11b WLAN systems under the toughest signal configurations within these standards. The power detector is temperature compensated on the chip, enabling a single-ended output voltage with excellent accuracy over a wide range of operating temperatures. The PA is biased by a single +3.3 V supply and consumes ultra-low current in the OFF mode. The AWL9224 is manufactured using advanced InGaP HBT technology that offers state-of-the-art reliability, temperature stability and ruggedness. The AWL9224 is RoHS (Restrictions on Hazardous Substances) compliant. It is provided in a 3 x 3 x 0.9 mm LPCC package optimized for a 50 system.
